Elizabeth Smart -- Shows Off New Husband ... and New Ring!

One day after tying the knot in Hawaii, Elizabeth Smart flaunted her brand new wedding ring while holding hands with brand new hubby Matthew Gilmour yesterday.

This is the first pic of the 24-year-old Brigham Young student since her Saturday wedding at a Mormon temple on Oahu's North Shore.

Smart and 22-year-old Gilmour dated for a year ... and were engaged for a month ... before tying the knot.

Smart made headlines back in 2002 when, at age 14, she was kidnapped from her home and held captive for 9 months by a sexually abusive psychopath. She was rescued after a biker noticed her abductor, Brian David Mitchell, attempting to conceal Smart's identity while traveling around Utah.

Last year, Mitchell was sentenced to life in prison for the kidnapping.
